The opencv-extra package

[ Tags: ai, bsd3, graphics, library ] [ Propose Tags ]

This is a Haskell library providing a binding to the OpenCV-3.x contrib modules. It binds directly with the C++ API using the inline-c Haskell library.

The library is far from complete but the framework is there to easily bind missing functionality.

Make sure to checkout the opencv-extra-examples.
